Name of the allele for the given gene. All gene-related features (exon, CDS etc) for a given gene should share the same Allele qualifier value; the Allele qualifier value must, by definition, be different from the Gene qualifier value; when used with the variation feature key, the Allele qualifier value should be that of the variant.

Reference to a citation listed in the entry reference field.

Database cross-reference: pointer to related information in another database.

A brief description of the nature of the experimental evidence that supports the feature identification or assignment.

Function attributed to a sequence.

Symbol of the gene corresponding to a sequence region.

Synonymous, replaced, obsolete or former gene symbol.

Genomic map position of feature.

A structured description of non-experimental evidence that supports the feature identification or assignment.

Gets the key for this item. These are not necessarily unique within a list, which is why this is a property of an object to be included in a list, rather than omitting this as a property and using a dictionary instead of a list.

A label used to permanently tag a feature.

Gets the location of this feature in the sequence. This may also refers to other genbank files. For example, join(100..200,J00194.1:1..150) In this example location specifies joining of bases from 100 to 200 from the sequence in which this location data present and bases from 1 to 150 from the sequence who's accession number is J00194.1.

A submitter-supplied, systematic, stable identifier for a gene and its associated features, used for tracking purposes.

Any comment or additional information.

A number to indicate the order of genetic elements (e.g., exons or introns) in the 5' to 3' direction.

Feature tag assigned for tracking purposes.

Gets the dictionary of attributes.

Accepted standard name for this feature.
